Answer:The answer is spinal cord
Explanation:
The central nervous system consists of the brain and the spinal cord.
The brain is the most highly specialized organ, and is protected by the skull or cranium, while the spinal cord is made up of soft tissue which runs from the medulla oblongata to the tail region. It is protected by the bones of the vertebral column.
The spinal cord acts as a PATHWAY between spinal nerves and the brain.
Answer:
B
Explanation:
The 3'-end of the reverse primer (3'-TTGGCCAATGG---5') is complementary to the forward primer (5'---AACCGGTTACC-3') and thus reduces the ability of the primers to bind to the targeted DNA sequence. There is possibility of hairpin loop formation or primer dimmers formation
Answer:
"Haploid" refers to any cell that has 23 chromosomes (half of the total 46). "Gametes" are specifically sex cells that have 23 chromosomes. "Diploid" refers to any cell that has all 46 chromosomes. "Zygote" is the result of two gamete (haploid) cells fusing, and becoming a diploid cell.
hope this helps!!:)
Explanation:
Nondisjunction - in nondisjunction, the chromosomes fail to separate at a proper state due to meiosis.
Deposition by the river replenishes soil in the wetlands with sediment and nutrients illustrates a positive effect that the Nueces River has on the wetlands.
Option: C
Explanation:
A river in its lower course leave the high elevated area and enters into the flat land. In the lower course of the river deposition is the prime work of a river. Estuary, delta are some of the landform that formed in the lower course of a river. Here, Nueces estuary is formed where Nueces river enters into the gulf.
In this gulf a wetland is formed which supports aquatic life and a dwelling place for them and land species also. Here, river deposits all its sediments and replenish the soil of wetland with new sediments and nutrients.
